Speaking from experience, after using the ball mill for a time, if the ball needs to be filled or replaced, the following two points can be used to determine whether the balls loading amount is reasonable.
During ball mill's working process, some loud noises will turn up.In general, ball mill has not noise in the production process.The emergence of the noise means there are definitely some problems in the ball mill.However, how can solve the noise problem, and the following we will talk about it.

Ball mill is used to grinding various ores and other materials, and tube ball mill is widely used in mineral processing equipment, construction and chemical industry and other national economic departments.This equipment is used to grind ore and other material with different hardness by drying method.They are the main powder grinding equipment widely served in metal ore dressing, building material industry and chemical industry.It gets its name for installing discharging grid plate at the discharging end.The equipment consists of driving part, rotating part, main bearing, feeding and discharging part, lubrication part and electric control part.
Ball loading capacity the volume of the grinding medium is the percentage of the effective volume of the mill, which is called the filling rate of the grinding medium.The size of filling directly affects the number of shocks, the area of grinding and the load of grinding medium in the grinding process.At the same time, it also affects the height of the grinding medium itself, the impact on the material and the power consumption.A kind of the ball loading capacity of the mill can be calculated according to the formula (1-14).Gra quantity of grinding medium, t.Rho s loose density of grinding medium, t/m3.Forged steel balls; p=s=4.5-4.8t/m3 cast steel balls p=4.3-4.6t/m3; rolling steel balls p=6.0-6.8t/m3; steel segments p=4.3-4.6t/m3_-filling ratio of grinding medium, when wet grinding: lattice ball mill pi = 40% 45%; overflow ball mill phi = 40%; rod mill phi = 35%.Dry grinding: when material is mixed between grinding media, the grinding medium expands, and when dry grinding is adopted, the material fluidity is relatively poor, material flow is hindered by abrasive medium, so filling rate is low, and the filling rate is between 28% and 35%.The pipe mill is 25%-35%.The void fraction of grinding medium_k=0.38-0.42 and the quality of crushed material accounts for about 14% of the quality of grinding medium.
Referring more particularly to fig.6b, where a cross-sectional view of the diverter gate assembly 650 is shown, it can be seen that a diverter blade 652 is designed to be pivoted between a first position and a second position, whereby the grinding balls 606 are guided to one of the diverter gates 654, and ultimately to one ball mill or another in order to maintain optimum grinding parameters in each of the ball mills.
ball mill liner the liner of cement dry-type ball mill can be divided into ceramic, granite, rubber, high manganese, magnetic liner and other materials.The function of liner is mainly to protect the cylinder from the direct impact of materials and steel balls and extend the service life.At the same time, the liner plate can also adjust the running track of materials.Generally, the head grinding bin is equipped with hard liner plate, which can enhance the impact force of materials and accelerate grinding.The liner plate of the fine grinding bin is corrugated liner plate or flat liner plate, which can enhance the grinding effect of materials.
The results show that under the same conditions of grinding fineness, the fluorite concentrate by rod mill obtains a lower si o2 content.Compared with ball milling, the particle size of rod grinding is more uniform, rod mill control the grinding fineness better.
(1)the lime and gypsum will be crashed and ball milled after entering the factory, batch production for this section working system.The raw materials is continuous crashed into grain which granularity is less than or equal to 25mm, and then be put in the storage respectively through 3-pass splitting by bucket elevator.Lime and gypsum-grain will be fed in proportion through speed belt scale and into ball mill for mixture levitation through the respective baiting splitting, when the fineness reached 3500 ~ 4000cm2 / g, the lime and gypsum-grain will be sent into cement silo through bucket elevator for storage.
In general, according to the grinding process and investors demand, manufacturers can provide customized grinding machine and ball mill with different output capacity.
The use of belt conveyor is not much, belt machine widely used in the dressing production line and sand production line, mainly responsible for all kinds of equipment such as crusher, ball mill, flotation machine between supply of raw materials, understand the belt conveyor belt conveyor working principle and operating rules for users to better understand and use of belt conveyor belt conveyor, henan mechanical engineer is the star to introduce some belt conveyor belt conveyor working principle and operation procedures.
